目的:探讨高海拔地区自发性蛛网膜下腔出血(SAH)的起病方式、发病时间、临床特点及诊治方法。方法:对101例SAH患者的临床资料进行回顾性分析。结果:101例患者中动态起病者81例(80%),发病高峰在2月和10月,低谷在9月、11月—12月。头痛、呕吐、脑膜刺激征仍为高海拔地区SAH的主要临床表现。结论:高海拔地区SAH的起病形式不一,临床表现多样,需行头CT及腰穿检查结合以减少漏诊率。对确诊患者需尽早行头CTA查找病因,DSA仍是明确病因的最直接可靠的方法。
Objective: To investigate the onset, time of onset, clinical features and diagnosis and treatment of spontaneous subarachnoid hemorrhage (SAH) in high altitude areas. Methods: The clinical data of 101 patients with SAH were retrospectively analyzed. Results: Among the 101 patients, 81 patients (80%) had dynamic onset, the peak incidence was in February and October, and the trough was in September and November to December. Headache, vomiting, meningeal irritation is still the main clinical manifestations of SAH at high altitude. Conclusion: The incidence of SAH in high altitude area varies from one to another. The clinical manifestations of SAH are diverse. Combined CT and lumbar puncture are needed to reduce the rate of misdiagnosis. As soon as possible to find out the cause of the CTA for patients diagnosed, DSA is still the most direct and reliable method of a clear cause.
